Instructions
Play through the game until you arrive in the mountain town Kravia. When you arrive, you'll find guards blocking your entrance. They tell you that you need the Kravia Pass to proceed.
Exit Kravia and travel south through the world map until you reach Darakin Citadel. You've already visited Darakin several times by this point in the game.
Walk down the main street until you reach the Green Lynx Inn. You'll hear an argument coming from within.
Enter the Green Lynx, prompting a cut-scene between the bartender and Sharon. As the cut-scene ends, she tells the party that she has a Kravia Pass. She then joins you.
